It +#   sets the PTHREAD_LIBS output variable to the threads library and linker +#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler +#   flags that are needed. (The user can also force certain compiler +#   flags/libs to be tested by setting these environment variables.) +# +#   Also sets PTHREAD_CC to any special C compiler that is needed for +#   multi-threaded programs (defaults to the value of CC otherwise). (This +#   is necessary on AIX to use the special cc_r compiler alias.) +# +#   NOTE: You are assumed to not only compile your program with these flags, +#   but also to link with them as well. For example, you might link with +#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +#   If you are only building threaded programs, you may wish to use these +#   variables in your default LIBS, CFLAGS, and CC: +# +#     LIBS="$PTHREAD_LIBS $LIBS" +#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +#     CC="$PTHREAD_CC" +# +#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with +#   PTHREAD_CFLAGS. +# +#   ACTION-IF-FOUND is a list of shell commands to run if a threads library +#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +#   is not found. If ACTION-IF-FOUND is not specified, the default action +#   will define HAVE_PTHREAD. +# +#   Please let the authors know if this macro fails on any platform, or if +#   you have any other suggestions or comments. This macro was based on work +#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +#   Alejandro Forero Cuervo to the autoconf macro repository. We are also +#   grateful for the helpful feedback of numerous users. +# +#   Updated for Autoconf 2.68 by Daniel Richard G. +# +# LICENSE +# +#   Copyright (c) 2008 Steven G.
